The flags of five countries have flown over that part of Wyoming which is now Park County—the flags of Spain, Great Britain, Mexico, France and the United States. For many years it was in Dakota Territory. With the birth of statehood in 1890, Wyoming, the 44th state, was divided into five counties running from north to south across the state. What is now Park County was first a part of Sweetwater County, then Fremont County, and then Big Horn County, until 1909, when the Wyoming State Legislature defined and set aside the boundaries of Park County. An election in November 1910 determined that the county seat would be in Cody. Records have been kept in Park County since 1911. In 2009, the collections were moved to the Park County Library in the Park County Complex.
